Description
Tregrylls is a farmhouse, likely dating from the mid-18th century, with a later extension added to the right in the late 20th century. It is constructed of slate stone rubble with granite quoins, featuring dressed stone flat arches over the ground floor openings and slate hanging above the ground floor on the front elevation. The roof is of scantle slate, with a gable end on the left and a half-hipped end to the right extension. A brick stack is present on the left hand gable end, and an axial brick stack originally served as an end stack on the right. The original plan is uncertain but likely consisted of a single-depth, two-room layout. The entrance is located to the right of the centre, with a larger room to the left and a smaller room to the right, both originally heated by end stacks. A late 18th or early 19th century outshut was added to the rear, and heated by a stone rubble lateral stack with a brick shaft. A one-room plan extension was added to the right hand gable end in the mid to late 20th century. The front façade is arranged with a regular 4:1 window arrangement. The ground and first floors both feature C20 replacement sashes. On the ground floor, there are two 12-pane sashes with flat dressed stone arches, a C20 stone rubble porch, and a wider 16-pane sash to the right, featuring a rusticated flat dressed granite arch and keystone. The extension on the right also has a 16-pane sash. The first floor has four 12-pane sashes, with a further 12-pane sash within the extension on the right. The interior is inaccessible. The estate of the Gryles was mentioned in 1303 when held by John de Grylls. Ownership subsequently passed from E.J. Glynn to Lord Churston and later belonged to the Betenson family, with several memorials to the family located in the churchyard of St Michaels, Lesnewth. Tregrylls occupies a prominent position within the unspoiled landscape of Lesnewth parish.
